Powered by Seiko's V192 solar chronograph movement, this Speedtimer delivers 1/5-second timing up to 60 minutes along with date, 24-hour and power-reserve displays, running for six months on a full charge. The 39 mm stainless steel case pairs a curved sapphire crystal and fixed tachymeter bezel with a white panda dial on a steel bracelet, and is water-resistant to 10 bar.
